Resolution of fluent dysphasia following excision of metastatic carcinoma from the arcuate fasciculus.

The effect of therapy on aphasic syndromes in patients with brain tumours is poorly documented. A case in which resection of a metastatic lesion led to resolution of a fluent dysphasia that had not responded to corticosteroid therapy is presented. As well as surgical and neurolinguistic interest this case demonstrates that CT diagnosis of malignant glioma can be erroneous and may lead to sub-optimal treatment.
